Description:
Much like it was the case for Southpark (Link to relevant topic), Steam won't launch the PoE public beta. It throws an error code 51 instead.
Expected behaviour:
Game launches.
Reproduce:
1. Install FSecure Antivirus and update it.
2. Try to launch Pillars of Eternity beta from Steam
Workaround:
Go to Antivirus settings and set "compatibility mode" for Deep Guard, or disable Deep Guard.
Fix: Obsidian should contact FSecure and register their game as non-virus or something like that...
